Modifying a Branch Circuit Family

This section teaches you how to work with branch circuit device families.

Start in the FIRST FLOOR POWER floor plan.

Modify the Family for the Elevator Motor

1.Select the elevator motor and run the Revit Edit Family command. The family file will open.

Modify | Electrical Equipment-> revit--edit-family Edit Family

2.Run the Family Edit command. The Family Edit dialog box will open.

DM Electrical-> dmert-family-16 Family Edit

3.Make the following changes to the family:
a.In the Family Settings section, set Device Type to Branch circuit device: Equipment connection.
b.Set MOCP to 40.
c.Set OCP Trip to Motor-compressor, <= MOCP.
d.Set Conductor to Size based upon loads.
4.Press the OK button to close the dialog box.
5.Run the Revit Load into Project command or Load into Project and Close command to update the family and its parameter values in the project.
You do not need to save the family file, but the parameters will only be used for this project if you do not save.
